how do you do substitution

1.	how do you do substitution
Answer» Substitution is process to solve equation. For example, consider two equations2x + y = 4 ....(1) x + y = 1 .... (2) We will use substitution process, so using eq (2) we can written as y = 1 - x, now substitute this in eq (1) 2x + 1 - x = 4x = 3 Therefore y = 1 - x = 1 - 3 = - 2. So, we saw an application of substitution

Answer»

Substitution is process to solve equation.

For example, consider two equations2x + y = 4 ....(1) x + y = 1 .... (2)

We will use substitution process, so using eq (2) we can written as y = 1 - x, now substitute this in eq (1)

2x + 1 - x = 4x = 3

Therefore y = 1 - x = 1 - 3 = - 2.

So, we saw an application of substitution
